Ok, let’s have a celebration! But why stay on Earth?
Let’s celebrate in orbit around Mars! How about that?
Mars is the fourth planet in our Solar System
and therefore our direct neighbor.
How about some Martian facts?
Mars is half as big as Earth and its distance
to the Sun is about one and a half time bigger than ours.
Although it looks completely different than our blue planet,
Mars belongs to the terrestrial, earth-like planets.
It’s reddish appearance brought him his name:
Mars — like the Roman god of war.
Today we know it
as the Red Planet.
The reason for the reddish color is quite unimpressive:
Iron(III) oxide on the surface of the planet and in the atmosphere
makes Mars look red, and Iron(III) oxide is simply ... rust.
Apropos atmosphere: Yes, there is one on Mars!
It contains more than 95 % of CO2 and it is very thin,
too thin to save the solar heat.
This causes a huge difference in temperature between day and night.
30 degrees centigrade at daytime sounds quite comfortable,
but at night the temperature sinks to about minus 85 degrees.
The thin atmosphere is also responsible for the inability of water
existing on Mars in fluidity; it only exists as ice or as water vapor.
Even though the living conditions on Mars are unfavorable,
we earthlings are very interested in Mars.
In our mind, a Martian is no longer
a tiny green fellow, exploring Earth.
A Martian is an earthling on Mars.
Because this is the target: a manned mission to Mars!
In the meantime we research, train and test.
We examine, collect data and samples, take pictures and map the surface of Mars.
Until today there were about 42 unmanned missions to the Red Planet.
The Soviets began in the early 1960s; without success ...
but in the early seventies NASA reached the planet.
About eight terrestrial vehicles
already touched down on "Red" ground.
In 2003 two NASA rovers named Spirit and Opportunity landed on Mars —
and both do their job until today: the search for water.
All of that is great, important and enlightening,
but not possibly record-breaking.
But remember: we wanted to celebrate something!
And right now, there is one great occasion to party!
The Odyssey Space Probe entered its orbit around Mars on 24 October 2001.
Since December 2010, Odyssey is the longest-serving space probe
humans ever sent to the Red Planet.
Congratulations and THANK YOU, Odyssey!
The probe, whose name was inspired by Stanley Kubrick,
created the most detailed map of the surface of Mars ever.
It consists of 22.000 single pictures and its resolution is 213.391 x 106.699 pixels.
So forget all terrestrial digital cameras!
The fuel of the probe will extend until 2015.
So Odyssey will be able to extend the lead
until we will finally be landing on the Red Planet as the first real Martians. �
